Li-Desiccants ke lintho tse monyang mongobo kapa metsi.Sena se ka etsoa ka mekhoa e 'meli e fapaneng haholo:
Mongobo o adsorbed 'meleng;mokhoa ona o bitsoa adsorption
Mongobo o tlanngoe ke lik'hemik'hale;ts'ebetso ena e bitsoa ho monya
Mofuta o tloaelehileng oa desiccant ke alumina e kentsoeng, sieve ea molek'hule, alumina silica gel
Adsorbent (papiso ea sekhahla sa adsorption)
Bophahamo ba Adsorption:
Alumina silica gel > silica gel > molecular sieve > activated alumina.
sekhahla sa adsorption: sieve ea molek'hule > aluminasilika gel > silica gel > activated alumina.
Re bolelle litlhoko tsa hau tsa tšireletso ea mongobo, 'me re tla khothaletsa desiccant e loketseng.Haeba sehlahisoa sa hau kapa lintho tse pakiloeng li hloka boemo bo tlase haholo ba mongobo, ho molemo ho sebelisa li-sieve tsa molek'hule.Haeba thepa ea hau e se na mongobo o fokolang, silica gel desiccant e tla etsa joalo.
① Adsorbent ka metsing, matla a khatello a fokotsehile, ho tlatsa ha ho thata
② tsamaiso ea khatello e lekanang ha e thijoe kapa e thibetsoe, phello e kholo haholo
③ tšebeliso ea ho tlatsa molamu o susumetsang, o amang matla a khatello ea sehlahisoa
Alumina e sebetsang: 160°C-190°C
Sieve ea molek'hule: 200°C-250°C
Jele ea silika ea alumina e hananang le metsi: 120°C-150°C
Mokhoa oa ho bala: ho tlatsa QTY = Ho Tlatsa Bolumo * Boima ba bongata
Ka mohlala, sete jenereithara = 2M3 * 700kg / M3 ＝ 1400kg
Tlhahiso ea naetrojene ea JZ-CMS4N ke 240 M3 / tonne motheong oa 99.5% N2 bohloeki, Kahoo sete e le 'ngoe ea tlhahiso ea N2 ke = 1.4 * 240 =336 M3/h/set
Mokhoa oa PSA O2: adsorption e hatellang, desorption ea sepakapaka, Re ka sebelisa JZ-OI9, JZ-OI5
Mokhoa oa VPSA O2: adsorption ea sepakapaka, vacuum desorption, Re ka sebelisa mofuta oa JZ-OI5 le JZ-OIL
